General information on DSTC

The stability and traction control system,
DSTC (Dynamic Stability and Traction Con-
trol) helps the driver to avoid skidding and
improves the car's traction.
The system limits the driving and brake force
of the wheels individually so that skidding
can be avoided. This increases manoeuvra-
bility and as a result safety in the event of
sudden movement.
Traction is improved by means of the system
distributing the driving force between the
wheels. The system primarily engages at low
speed on poor road surfaces.
The activation of the system during braking
may be noticed as a throbbing sound. The
car may accelerate slower than expected
when the accelerator pedal is depressed.

Messages in the information display

DSTC Temporarily OFF
System temporarily reduced due to exces-
sive brake disc temperature. The function is
reactivated automatically when the brakes
have cooled.
DSTC Service required
System disabled due to a fault.
Stop the car in a safe place and turn off the
engine. If the message remains when the
engine is restarted, drive to an authorised
Volvo workshop.
Symbols in the combined instrument
panel
If the symbols and are displayed at
the same time, read the message on the
information display.
If the symbol appears alone then it may
appear as follows:
• Flashing light means that the system is
now being activated.
• Constant glow for 2 seconds means sys-
tem check when the engine is started.
• Constant glow after starting the engine or
while driving means system fault.

Reduced operation

System operation during skidding and accel-
eration can be reduced. Operation during
skidding is delayed and so allows more skid-
ding which provides greater freedom for
dynamic driving. Traction in deep snow or
sand is improved as traction is no longer lim-
ited.
